Thinner to remove oils and SEM to paint
I rubbed my mount down briskly with paint thinner to remove all grease and oils. Held a blow dryer to it to dry off the thinner and painted it while it was still a little warm.
I used "SEM Color Coat" Flexible Coating Paint. Got it at a local paint store that specializes in Automobile paints. The can says it "changes or renews color on most flexible and rigid plastics, carpet, vinyl and velor". Can is labled to NOT be for sale to the general public and says it should be applied by professionally trained personnel with proper equipment. It's got some nasty chemicals inside, but WOW does it work well. I used a respirator because I have one - like having safety glasses on the shelf and not using them. Good ventilation would probably be ok.
My interrior is a light charcoal grey. I used color #15163 Presidio. Two light coats. Both the finish and the color came out exceptional.
I've tried expensive etching undercoats (Bull Dog Adheision Promoter) before painting my ATV's and nothing seems to penetrate the hard, slick plastic fenders. The paint still scrapes off easily. I was SO impressed with this SEM paint that I'm going to try it on the ATV's next go around. If the SEM doesn't work, I might start thinking that only a dye would work. Anybody know of anything that sticks well to ATV plastic?
Good luck with your paint job.
